An upright for shelving, racks &amp;c. has a core consisting of an I-section steel member with flanges 7 folded inwardly to form recesses 2a opening to the outside through rectilinear gaps, the assembly being effected by bolting or welding two plate elements 1, 1 symmetrically. In each recess 2a a double rack section 3a is slidably engageable and is of U-section with spaced slots 4 to receive the suspension hooks of brackets and has a central rib 6. Specification 916,961 is referred to.

No.2%,719 Claims priority, application France, July 26, 1%2, 95,17 1 Claim.(Cl. 52-732) The present invention concerns vertical elements oruprights consisting of steel cores with light-alloy sections.

An upright is formed by equipping the core, i.e. by slidably engagingtherein one or two light-alloy sections each formed with at least onelongitudinal series of aligned holes, each hole being disposed betweenadjacent longitudinal ribs projecting to the exterior.

According to the present invention, the sections fit in cavities formedin said cores and communicating with the outside through rectilineargaps through which the ribs of said sections project.

With this construction particularly strong uprights can be made whichare especially suitable for constructing rack or like collapsible piecesof furniture intended for supporting relatively heavy loads.

The features and advantages of this invention will appear morecompletely and clearly from the following description given by way ofexample with reference to the accompanying drawings, in which:

FIGURE 1 is a section taken across the steel core;

FIGURES 2 and 3 are cross-section and front elevational views,respectively, of a light-alloy section, and

FIGURE 4 shows in cross-section an upright consisting of a steel core incombination with a pair of lightrnetal sections.

There is provided a core consisting of two channel shaped elementsassembled symmetrically to form a web 1 as shown in FIG. 1. The assemblymay be effected either by spot-welding or by bolting. The web 1 has ateach end a pair of opposed channel-shaped flanges 1a and 11) formingtubular recesses 2a. The free marginal edges of each pair of opposedchannel-shaped flanges 1a and 1b are spaced from each other to provide arectilinear gap 7.

In each recess 2a a double-rack light-alloy section 3a, shown in FIGS. 2and 3, is engageable in smooth sliding contact. The section 3a hasformed on its front face two rows of holes 4 having lateral ribs 5 and 6disposed on either side, the holes 4 being long enough and sufficientlyspaced from one another to receive bracket suspension hooks ofrelatively large dimensions.

FIGURE 4 shows an upright consisting of a core 1 associated with a pairof light-alloy sections 3a. On each section 3a the ribs 5 and 6 projectexternally through the rectilinear gaps 7, the gaps 7 permitting accessto the holes 4.

What I claim is:

An upright element for constituting convertible, superposable andjuxtaposable pieces of furniture adapted to be quickly assembled anddisassembled, said element comprising a core and at least onelight-alloy section, said core consisting of a web having a pair ofopposed channelshaped flanges forming a tubular recess at each end ofthe Web, the free marginal edges of the opposed channelshaped flangesbeing spaced from each other to provide rectilinear gaps, saidlight-alloy section slidably engaging one of the tubular recesses ofsaid core and having at least one longitudinal series of holes andlongitudinal ribs disposed on either side of the longitudinal series ofholes, said ribs projecting to the outside through the rectilinear gapof said recess whereby said rectilinear gap permits access to saidholes.
